DGS-Based Wideband Microstrip Antenna for UWB Applications
springer
摘要
For UWB applications, a circular monopole having minimal dimensions has been designed for operation at single band. Half circular strip with semicircular monopole having smiley and DGS is the main features for this antenna, consisting of a mixer of semicircular element for radiation and similar strip along with a smiley on the top side of the substrate with permittivity 4.4 and thickness h = 1.59 mm. The bottom side a dumbbell-shaped DGS is incorporated. The proposed antenna has advantage in enhancing antenna bandwidth. This work is carried out using CST software.
